Step-by-step explanation:

Answer:
x = 7, x = -3
Step-by-step explanation:
We can find the zeros by factoring the equation using the zero product property.
x^2-4x-21 = 0
(x-7)(x+3) = 0
<u>x-7 = 0</u>
x = 7
<u>x+3 = 0</u>
x = -3
Zeros are x=7 and x= -3.
Answer:
288
Step-by-step explanation:
24 = 8 1/3 % of x
24 = (25/3 * 1/100)x
25/300 x = 24
x = 24 * 300/25
x = 7200/25
x = 288
